See Benson, supra note 62a, at 647 ("[D]uring this period, because of the need for uniform laws of commerce to facilitate international trade, . . . the basic concepts and institutions of modern Western mercantile law--lex mercatoria--were formed, and, even more important, it was then that mercantile law in the West first came to be viewed as an integrated, developing system, a body of law'. Virtually every aspect of commercial transactions in all of Europe (and in cases even outside Europe) were governed' by this body of law after the eleventh century. . . . This body of law was voluntarily produced, voluntarily adjudicated and voluntarily enforced. In fact, it had to be. There was no other potential source of such law, including state coercion.").
